Hi,
I'm trying to find all my computers on my home network (ip addresses are
assigned using DHCP, can't change that). So far these are my attempts:
$ ip neigh | grep REACHABLE | grep <mac_address>
But this seems rather unrealiable. Often the reported addresses are not
up to date (e.g. offline devices still show up, or newly connected
devices are missing). I also tried nmap with the DHCP ip range:
$ nmap -sn 192.168.1.65-150
But that is too intensive (I intend to run this from a script in a cron
job from time to time); also I do not know how to get the mac_address so
that I can identify which device it is.
Can someone point me in the right direction?
Use fping -g ....
